Comparative Analysis of Pedigree-Based BLUP and Phenotypic Mass Selection for Developing Elite Inbred Lines, Based on Field and Simulated Data

Pedigree-based best linear unbiased prediction (pBLUP) is an effective method for genetic evaluation. The objective of this study was to assess the efficacy pBLUP develop superior inbred lines, using field and simulated data. This based on data 30,986 plants from six S0 generations eight progeny trials (S1–S4), performed over years. We measured grain yield expansion volume (EV). also EV 5000 (S0–S4) in two silico populations, assuming 300 400 genes distributed across 10 chromosomes 200 cM, respectively, 10% pleiotropic genes. selected selfed predicted additive value by fitting individual model population. use provided total gains range 1 45%, inversely proportional level improvement population, indirect changes −17 3%. Only analysis selection true gain computed genotypic values, there evidence that phenotypic mass selection.
